Michael J. Fox is the latest celebrity to mourn over Robin Williams‘ suicide.
Not only were Michael and Robin friends, but the pair shared a commonality that Michael didn’t even know about until it was too late.
That bond, as we reported yesterday, was that both actors were suffering from Parkinson’s Disease.
Michael, who has been dealing with PD since the early 1990s, took to Twitter to address finding out about Robin’s previously-unpublicized diagnosis, saying:
Stunned to learn Robin had PD. Pretty sure his support for our Fdn predated his diagnosis. A true friend; I wish him peace.
